High-density material offers ample support and water retention for plants of any size, and ensures that the blocks will maintain their shape during handling. Sterile, UV-blocking wrapper protects roots and fits tightly to keep water and nutrients in the root zone. Specially-developed wetting agent provides efficient, uniform saturation and optimized nutrient uptake with a water holding capacity of 85-95%. Pre-cut squares ensure perfectly uniform, repeatable spacing for grow blocks-no measuring or guesswork required. Rockal Blocks are manufactured from at least 70% recy- cled material.
Excellent water holding capacity Higher substrate volume for extra root growth Uniform WC and EC throughout the block Improved control and steerability Solid base for top-heavy plants Larger yields.
